WEM Power Musette Mk II - Normal preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Power Musette Mk II is a small WEM valve amp that shares its circuit with the Dominator Mk III and Dominator Bass Mk I. Two channels each run an ECC83 gain stage into their own Treble and Bass controls, a second triode stage and their own Volume, with a Bright switch on one channel. An ECC83 long-tailed-pair phase inverter drives two EL84s for 15 watts into a 12-ohm output, from a BY127 silicon-diode rectifier.
